HEATING FEED-WATER FOR MOTOR-VEHICLES.

SPECIFICATION forming part of Letters Patent N 0. 722,309, dated March 10, 1903. Applicationfiled January 29, 1902. Serial No. 91,738- (N'o model.)

To all whom it may concern.-

Be it known that we, WILLIAM J AMES LANE and GEORGE LANE, citizens of the United ing Feed-Water for Motor-Vehicles, of which the following is a specification.

Our invention relates more especially to certain new and useful improvements in feed-water heaters, such as are adapted for use with motor-vehicles.

The object of our invention is to provide simple and efficient means for heating the feed-water fed to the boiler, for muffling the steam fed to the feed-water heater, for delivering into the water-tank the water of condensation from the steam fed to the feed-water heater, for maintaining the lubrication of the engine, and for creating a downdraft from the boiler.

The accompanying drawings will serve to illustrate our invention and in whichsimilar letters indicate like parts.

Figure 1 is a longitudinal vertical section on the line 1 1 of Fig. 2. Fig. 2 is a plan view and partial section on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal section through the niuffler-druni.

In the drawings, A represents a steamboiler; B, water-tank; O, steam-engine; D, main steam-pipe-from boiler to engine; E, closed muffler-drum located in the present instance below the water-tank. It may, however, be given any suitable location. F is an exhaust-pipe from engine discharging into the top of the muffler-drum; G, water-supply pipe from water-tank to boiler. The pipe G starts from the bottom of the water-tank, is

formed as a coil H within the muffler-drum E,

and is connected to the induction-orifice of the water-pump I. A corresponding pipe is connected to the eduction-orifice of such pump and to the boiler A.

Connected to the bottom of the mufflerdrum E is a pipe J, adapted to discharge within the water-tank B. y

K is a vent-pipe for the water-tank; L, exhaust-pipe from muffier-drum E, discharging into down-flue M from the boiler.

The operation of our device is as follows:

The exhaust-steam from the engine, which carries with it a certain amount of oil used in lubricating the engine, is fed into the upper part of them uflier-d rum Eand fills such drum. A small portion of this steam escapes by the pipe J into the water-tank B. The feed-water from the tank passing through the pipe G, under the action of the pump I, traverses the coil H within the drum E and is heated. The steam within the drum E is partially condensed by the temperature of the water passing through the coil H and collects as heated water and oil in the bottom of the drum E, from which it is expelled by the action of the exhaust-steam through pipe J into the Water-tank B. At the same time a portion' of the exhaust-steam discharged into the muffler-drum E passes by pipe L and is discharged into the down-flue M, creating a draft in such down-flue M from the boiler.

It will be observed that the lubrication of the engine is maintained by the oil carried from the engine to the water-tank, and thence through the pump back to the boiler, and from the boiler to the engine. In practice it has been found that such oil acts as an effi cient lubricant and does not in any wise in terfere with the action of the boiler.

It will be understood that owing to the size of the pipe L, as well as the friction between the exhaust-steam and the pipe, a back pressure will be created in this pipe and the drum E, which will be sufficient to overcome the weight of the water to be lifted from the drum E into the water-tank B, in practice about one pound pressure.

We wish it understood that we do not limit ourselves to the precise arrangement of parts shown in the accompanying drawings, as very many changes may be made therein without departing from the intent of our invention as, for instance, the exhaust-steam may be fed to the muffler-drum at two or more points instead of at one point, and a portion of the exhaust-steam may be carried, to and discharged into any fine leading from the boiler which conveys away the products of combustion.

Having thus described our invention, we claim- 1. In a motor-vehicle, the combination of a water-tank, a steam-generator, apipe leading from the water-tank to the steam-generator, a drum inclosing a portion of said pipe and located below the level of the water-tank, a source of steam connected to said drum, a pipe connected to the bottom of the drum and discharging into the water-tank, and a discharge-pipe leading from the drum, such pipe of the required size to normally create sufficient back pressure to cause the steam discharged into the drum to lift the water of condensation from the drum into the water-tank.

2. In a motor-vehicle, the combination of a Water-tank, a steam-generator, a pipe leading from the bottom of the water-tank and discharging into the steam-generator, a drum located under the Water-tank, within which a portion of said pipeis coiled, asource of steam connected to said drum, a pipe leading from the bottom of said drum, carried upward and adapted to discharge into the top of the Water-tank, an exit-flue for the products of combustion from the steam-generator, and a pipe leading from the drum and having its discharge-nozzle located in said exit-flue.

3. In a motor-vehicle, the combination of a water-tank, a steam-generator, a pipeleading from the water-tank to the steam-generator, a drum inclosing said pipe and located below the level of the water-tank, a source of steam connected to one end of said drum, a pipe connected to the bottom of the drum and discharging into the water-tank, an exit-flue for the products of combustion from the steamgenerator, and a pipe leading from the opposite end of the drum and discharging into the exit-flue.

4. In a motor-vehicle, the combination of a steam-generator, a closed water-tank, a ventpipe from said tank through which any excess of water may be discharged, an engine, a feed-water heater between the steam-gener ator and water-tank, means for conveying steam from the engine to the feed Water heater, and means for picking up the condensed steam in said feed-water heater, lifting it and discharging it into said water-tank.

In testimony whereof we affix our signatures in the presence of two witnesses.
